DEFINITIONS:
Total VAP refers to the total Voting Age Population of the State as reported by the Bureau of Census. Please note that the VAP includes all persons over the age of 18 -- including a significant number of people not able to vote in U.S. elections.
Total REG refers to the total number of registered voters as reported by the States.
*TURNOUT in this instance turnout refers to the total vote cast for the highest office on the ballot (President). These figures may be inconsistent with other reported turnout figures since research suggests that approximately 2% of voters fail to vote for the highest office on a fairly consistent basis.
N/A means Not Applicable. North Dakota has no voter registration and Wisconsin has election day registration at the polls.
UNK means Unknown
